The Square Enix PSP role-playing game
Kingdom Hearts: Birth by Sleep led weekly Japanese software charts for the second week in a row, tracking firm
Media Create said this week.
For the week ended January 17,
Kingdom Hearts: Birth by Sleep sold 177,000 units, down from the prior week's two-day total of 446,000. On its release, the game, launched January 9, also was able to
boost PSP hardware sales significantly.
Kingdom Hearts: Birth by Sleep is a prequel to the 2002 PlayStation 2 game
Kingdom Hearts, which launched the RPG series that mixes Disney and Square Enix characters. Square Enix has yet to announce a release date for the U.S. market.
New Super Mario Bros. Wii followed at number two for another week. The game has been near or at the top of Japanese software sales charts since its release on December 3 last year, and managed to sell 139,000 for this most recent week.
Three new titles launched that managed to break the top 10 during the period: Capcom's Wii light gun game
Resident Evil: The Darkside Chronicles, Namco Bandai's PSP fighter
Tekken 6, and the Nintendo-published DS adventure game
Last Window: Mayonaka no Yakusoku, a sequel to 2007's
Hotel Dusk: Room 215.
